Thanks for confirmation. It's a bit weird that your Juno board doesn't produce all zeros for timestamp packets.
I think the issue is that ls is quite quick to run, so not much trace is generated for Perf. And it just depends on the scheduling which is slightly different on Juno. I don't think it's a bug. On N1SDP there are only 134 samples generated with i1000i, so it could probably end up with a random run generating 0 there too.
Agreed, changing to smaller interval makes sense for me.
